The polyatomic ions

The polyatomic Ions

There are 3 with a -2 charge

SO42– …..Sulfate

SO32– …...Sulfite

CO32– ……Carbonate


So 4 2

SO42–

Sulfate


So 3 2

SO32–

Sulfite


Co 3 2

CO32–

Carbonate


There is only 1 with a 1 charge

There is only 1 with a +1 charge

NH41+……. Ammonium


Nh 4 1

NH41+

Ammonium


There are several with a 1 charge

There are several with a -1 charge

ClO41–…perchlorate

ClO31–…chlorate

ClO21–…chlorite

ClO1–…hypochlorite

Do you see a pattern?


One of these is nitrite the other is nitrate

One of these is nitrite the other is nitrate

NO31–……………….

NO21–……………….


More 1 charges

More -1 charges

HCO31–…Bicarbonate

HSO41–…Bisulfate

HSO31–…Bisulfite

Do you see a pattern?


More 1 ions

More -1 ions

OH1–……..…Hydroxide

CH3COO1–………….acetate (also C2H3O2-1)

MnO41–……….permanganate


And there is only one 3 ion

And there is only one -3 ion

PO43–……………….phosphate
